| 摘 要： | 以最小化条件风险价值CVaR为目标函数,考虑资金限制,建立套期保值模型来研究多品种期货套期保值的套保比率问题。以资金限制为约束,避免了套期保值者因资金短缺而强制平仓造成的套保失败。实证结果表明,多品种的单位风险收益比单品种的大,说明多品种较单品种能更好地实现套期保值。

| Abstract: | Conditional value at risk of hedging was taken as an objective function to achieve its minimum,a multi-spot commodity future hedging decision-making model was set up based on capital constrain to solve the problem of hedging ratio.This model considers the influence of capital constrain to avoid forced liquidation due to shortage of funds which results in hedging failure.The empirical results show that the return of multi-spot commodity future hedging is bigger than that of single future hedging,which explains why the former can better realize hedging than the latter. |
